Problems solved by technology

At present, leather products on the market already have the characteristics of excellent performance, novel style and rich colors, but due to the limitation of processing technology, leather products are usually "uniform" in style and color, for example, leather products of the same style and color (such as There will be no obvious difference in the appearance and feel of luggage), and it will be difficult for consumers to reflect their individuality during use, and even embarrassment of "crash". In this case, even very high-end products will have great quality and effect. discount

Embodiment 1

[0028] The invention discloses a leather processing method, which includes processing degreasing and dehairing raw hides: liming, deliming and pickling, tanning, retanning and bottom dyeing, stretcher drying, finishing, and varnish spraying.

[0029] In the above-mentioned process, the described finishing process is as follows:

[0030] Raw material formula of rosin liquid:

[0031] The raw material composition of the rosin liquid is (% by weight): 10% rosin, 85% ethanol with a concentration of 75% (v%) and 5% preservative.

[0032] Finishing process:

[0033] Spray the above-mentioned rosin solution on the front surface of the dry leather base that has been dried by stretching on the table, and then paint the surface of the leather base that has been sprayed with the rosin solution, and dry it naturally. After the above-mentioned finishing process, it is also The leather blank sprayed with rosin liquid can be sprayed with varnish to complete the processing process. The fina...

Embodiment 2

[0035] The leather processing method in embodiment 2 is consistent with embodiment 1, and the raw material formula of rosin liquid is changed.

[0036] Raw material formula of rosin liquid:

[0037] The raw material composition of the rosin liquid is (% by weight): 15% rosin, 80% ethanol with a concentration of 60% (v%) and 5% preservative.

[0038] Finishing process:

[0039] Spray the above-mentioned rosin solution on the front surface of the dry leather base that has been dried by stretching on the table, and then paint the surface of the leather base that has been sprayed with the rosin solution, and dry it naturally. After the above-mentioned finishing process, it is also The leather blank sprayed with rosin liquid can be sprayed with varnish to complete the processing process. The final leather blank shows a unique leather texture style, forming a texture pattern that is natural, interlaced, and rich in changes. Irregular clusters of cracks, which can change during the...

Embodiment 3

[0041] The leather processing method in embodiment 3 is consistent with embodiment 1, and the raw material formula of rosin liquid is changed.

[0042] Raw material formula of rosin liquid:

[0043] The raw material composition of the rosin liquid is (% by weight): 10% rosin, 80% ethanol with a concentration of 85% (v%) and 10% preservative.

[0044] Finishing process:

[0045] Spray the above-mentioned rosin solution on the front surface of the dry leather base that has been dried by stretching on the table, and then paint the surface of the leather base that has been sprayed with the rosin solution, and dry it naturally. After the above-mentioned finishing process, it is also The leather base sprayed with rosin liquid can be sprayed with varnish, that is, the processing process is completed. The final leather base shows a unique leather texture style, forming a texture pattern that is natural, interlaced, and rich in changes. Irregular clusters of cracks, which can change ...

Abstract

The invention provides a leather and a leather product, and a processing method thereof. The processing method comprises the following treatments on a defatted and depilated raw hide material: liming, deashing pickling, tanning, retanning and bottom dyeing, toggling drying, finishing, gloss oil spraying. The finishing process is as below: spraying a rosin liquid on the front of a dry hide blank subjected to toggling drying, and then painting the hide blank surface sprayed with rosin liquid, and naturally drying. Through improving the finishing process, the invention endows the leather surface with varied cracks, so as to produce different visual and sensory effects.

Description

technical field [0001] The invention relates to leather and leather products and a processing method thereof, belonging to the technical field of leather processing. Background technique [0002] The leather industry is closely related to human life and the development of the national economy, and is a pillar industry of light industry. At present, leather products on the market already have the characteristics of excellent performance, novel style and rich colors, but due to the limitation of processing technology, leather products are usually "uniform" in style and color, for example, leather products of the same style and color (such as There will be no obvious difference in the appearance and feel of luggage), and it will be difficult for consumers to reflect their individuality during use, and even embarrassment of "crash". In this case, even very high-end products will have great quality and effect. discount. With the continuous improvement of consumption concepts, p...
